yes other people just say that some issue with the GSM module....
but maybe someone can edit some registry to change the string in the radio rom....
like the olipro unlocker he can make string in the radio rom to add frequency for US GSM....

so to anyone who can make the radio rom setting to add new setting frequency to the default setting....
i hove someone can help me with this thing's.....
